Despite the many benefits of physical activity, postnatal women are not currently meeting Health Canada Guidelines of 150 minutes per week of moderate-vigorous physical activity. This study, Move More Mommy, used a mixed methods design to test the feasibility and acceptability of a web-based intervention combined with a group mediated cognitive behavioural approach, and it’s effectiveness to increase physical activity, self-efficacy, and group cohesion among postnatal women. Participants received an 8-week intervention delivered through 8 group exercise classes and a purpose built website. From baseline to post-intervention, participants significantly increased self-reported physical activity levels and group cohesion. Objectively measured physical activity levels and self-efficacy showed no significant change. Quantitative and qualitative data on feasibility and acceptability showed that this method of delivery is feasible and acceptable among postnatal women and provides preliminary evidence on the effectiveness of a web-based physical activity intervention for postnatal women.
